Part definition
Include your part number and drawing revision. Attach the 2D drawing and, where useful, a 3D model. For an existing part without drawings, send photos, key measurements and information about a physical sample.
Host and installation
Identify the plastic specification, receiving hole, surrounding boss and proposed installation method. If you have not chosen a route, explain the assembly and available process.
Material and interface
Specify insert material, thread or bore, finish, mating hardware and the dimensions that control the fit. Call out requirements that are not visible in a model.
Quantity and timing
Separate sample quantity, first order and expected repeat demand. Give the delivery destination, required date and any packing or labeling requirements.
Inspection and approval
List the critical dimensions, material documents, thread gauges, sample approval and functional tests needed. Agree how a revision or substitution will be reviewed.
